<h2>
Cost savings in using the fluorescent bulb is 3.81 cents</h2>
Explanation:
A 100 watt incandescent light bulb is operated for 7 hours.
Energy used by 100 watt incandescent light bulb = Power x Time
Energy used by 100 watt incandescent light bulb = 100 x 7 = 700 Wh
Energy used by 100 watt incandescent light bulb = 0.7 kWh
A 32 watt fluorescent light bulb is operated for 7 hours.
Energy used by 32 watt fluorescent light bulb = Power x Time
Energy used by 32 watt fluorescent light bulb = 32 x 7 = 224 Wh
Energy used by 32 watt fluorescent light bulb = 0.224 kWh
Cost of electricity per kWh = 8 cents
Cost of electricity by 100 watt incandescent light bulb = 0.7 x 8 = 5.6 cents
Cost of electricity by 32 watt fluorescent light bulb = 0.224 x 8 = 1.792 cents
Difference in costs = 5.6 - 1.792 = 3.808 cents
Cost savings in using the fluorescent bulb is 3.81 cents
Ooh punnett squares

I think the answer is ruthorford
The time taken by traveler to cover the distance is,
Substitute the known values,
Therefore, the time taken by traveler to cover the distance is 89.3 s.
The answer is B.)
This is because for years scientists have build up and found discoveries that led to recent discoveries brought by previous scientists.
Hope this helps
